ASSIGNORS TO OXFORD VARN'ISH CORPORATION, OF DETROIT, MICHIGAN, A. OOR-PORATION OF MICHIGAN APPARATUS FOR-DECORATING INSIDE SURFACES OF FRAMESAND THE LIKE Application led J'uly 17,

This invention is concerned with an apparatus for decorating articles,such as hollow frames, on the interior surfaces thereof, an example ofsuch work being sheet metal window frames for closed automobile bodies.These frames include substantially contiguous sides which, for thedesired inside surface inish, may have imparted thereto a wood or othergrained pattern effect. The hollow frame units are of various sizes andsometimes various shapes; usually they are rectangular and completelyClosed on all four sides,'that is, all sides are contiguous with twoadjacent sides. Frames of this sort have previously been grained ontheir inside surfaces by tedious hand methods with more or less success,but it has been found practically impossible to hand grain such frameson a high production basis.

An object of this invention is to provide an efhcient apparatus fordecorating the inside surfaces of generally hollow articles. By theterms hollow, or generally hollow articles, as herein used, U-sh'apes,etc. are included.

Another object is to provide an eicient machine for decorating,specifically, graining, the inside surfaces of metal frames havingcontinuous or substantially continuous side members.

Other objects and features of the invention will become apparent fromthe following description relating to the accompanying drawings, showingthe preferred forms of the apparatus and machine and illustrating thevarious steps of the method as prefcrably practiced. The essentialcharacteristics are summarized in the claims.

is a sectional detail view substantially according to the line 5-5 onFig. 4; Fig. 6 is a detail view showing certain other scrapermechanisms, the section being taken substantially along the line 6--6 onFig. 2; Fig. 7 is a detail view of a portion of the work support andguide arrangement in substantial accordance with the line 7--7 on Fig.2; Fi s. 8 to 11 are diagrammatic illustrations of-t e preferredsequence of steps in carr ing out the method; Figs. 12 and 13 areiagrammatie plan views of still other forms of apparatus or machines bywhich the method may be carriedv intol effect, and Fig. 14 is anexemplary plan view of a different form of frame, such as maybe grainedor decorated in accordance with the invention.

In general, the method of handlingholl tion is effected, will move theframe fromone position to another relative to the support and willfinally free the frame, allowing the latter to be shifted to a differentposition on the support for subsequent engagement by rolling contactwith, for example, another segment. In this manner, all the insidesurfaces of the frames may be grained, notwithstanding the fact thatsome of the elements or sides of the frames are of different lengths, infact. shapes. The machine is arranged to adequatelysupport the frames ineasily handled position, and a feature of the machine is that all of thepattern transferring surfaces of the segments are effectively cleaned ofexcess pigment material and new pattern effects placed on the transfersurfaces in an ex editions manner. Further refinements inc ude theprovision of cleaning arrangements for the various Scrapers, whereby thelatter will 0 erate with maximum efficiency to remove t e excess pigmentfrom the transfer material.

Referring in detail to the drawings, 1 indicates a rotary table or headsupported on a suitable axle 2 carried on4 a general frame which, asshown, comprises standards 4 and 5, a top yplate 6 and a base 7. Thetable or head may, of course, be supported in any other position, ratherthan horizontally, as shown. The support for the axle 2 is best shown inFig. 3 and comprises an upper bearing bracket 8 for a suitable bearing9, the bracket being inserted into the top plate 6 from the bottom sidethereof and secured in any suitable manner, as by means of flanges 8' onthe bracket. The bottom end of the axle is support by a bracket 10which, 'as shown, carries a radial thrust ball bearing at 11 and avertical thrust ball bearing at 12. The bracket 10 may be secured infixed position on the base plate 7 in any suitable manner, as by flanges10. e

The table in the form shown in Figs. 1'to 7 has a central webbed body,including a hub 15 and machined pad surfaces, such'as 16, for thetransfer material supports and other devices, to be later described. Asshown, the surfaces 16 support transfer segments at 20 and 21, thesebeing arcuate in form, presenting outer cylindrically formed surfaces 20and 2,1', the surfaces being generated on arcs radiating from the axle2. At the opposite glue and glycerine.

ends of the segments, there are downwardly diverging surfaces 20 and 21,respective to the segments 2O and 21. Any suitable means mayA be usedtol support these segments and the material of the segments ispreferably the usual transfer material, such as congealed Such materialmay be cast inthe form shown, that is, in arcuate segments, suitablyfinished to provide the surfaces 20,20, etc., or may comprise generallyflat strips of suitable transfer material fastened to suitable rigidbases to cause the ma- A terial to hold its shape. The segmentsreferably comprise cast sections or unitso suitable lengths onindividual cores, such as Wood or the like, these being in the form ofstrips indicated at 22, there being end blocks for the strips suitablyfastened thereto or integral therewith, the end blocks indicated at 23in all fi res. The end surfaces presented by the b ocks 23 conform ingeneral to the surfaces 20 and 21" of the respective segments.

For holding the segment units above described onto the table, there areprovided flanged, arcuate attaching brackets 25 suitably bolted orotherwise secured to the machined surfaces 16 and arranged to rigidlysupport the transfer segment cores, as by up# `right flan es 25. Thebrackets may have suitable a justment and are interchangeablefersurfaces of the segments are smooth and separate pattern app yingmechanism 30 1s provided, at the rear of the table 1, as shown. Thismechanism is carried on a rearwardly extending bracket 31, secured tothe uprlght frame member 5 and carries a pattern r oll at 32. i Thepattern roll may be of'any suitable construction and carries on itsouter surface thedesired pattern; for example, it may comprise acontinuous etched intaglio plate in cylindrical form. Such aA roll maybe made in accordance with the patent to J. P. Henry No. 1,548,465,issued August 4, 1925 assigned lift screw, the position of which isindicated at 35, and which may be driven from the roll 32 by anysuitable means. As shown, the roll is supported on a vertical shaft 36in base and /top plate members 37 and 38 respectively, and the shaft 36carries a gear 39 meshing with a small spur pinion 40 (see Fig. 2) todrive the screw. The base plate 37 may be adjustably mounted, as inslideways 42 on the bracket 31, (see Fig. 2) to govern the pressurebetween the pattern roll and the transfer segments. This adjustment maybe effected and the position maintained in any suitable manner, notshown.

For scra-pingthe excess pigment from the intaglio plate on the patternroll, there is shown a suitablescraper device, including a scraper blade43 yieldingly mounted on a vertically slidable frame 44 carried on asuitable post 45, see Fig. 3. As shown, there is a sprmg 47 connectedwith an arm 48 which is in turn connected with'the scraper mounting 44for yieldingly'urging the scraper blade into scraplng contact with theroll.

Suitable means for driving all the above described mechanism is shown inFig. 3 and may comprise a counter shaft 50 supported in `suitablebearing brackets, such as 51 and 52, below the table and top plate. Theshaft 50 may be driven in any`suitable way, as by a sprocket chain l52connecting sprockets 53 and 54, the former being carried rigidly on theshaft 50, and the'latter being connected with the driven element of asuitable reduction gear unit 55, of known construction, -which is inturn driven, as by means of a belt 56, from a suitable electric motor57, the reduct-ion gear unit and motor being mounted 1Q on the baseplate 7 as shown. To drive the table 1, we provide a bevel gear cou le,including a driving pinion 60 on the s aft 50 and a cooperating gear 61fast on the axle 2 of the table. To drive the pattern roll, there isprovided a driving pinion 62 on the shaft 50 and a cooperating pinion 63on a stub shaft 64 forming, in effect, a part of the shaft 36 forl thepattern roll. The shaft 50 may also reciprocate the scraper blade 43 forthe pattern roll through the agency of a cam 65 on the shaft 50 coactingwith a follower 66 sup rted in a suitable bracket 67 below the sha t 45,previously mentioned. The follower 66 pushes upwardly under the actionof the cam on a slidin cap 68 carried freely on the lower end of t eshaft 45, and the cap may be connected as by a series of sliding pins 69with the frame 44, which supports the lade. The blade may be returnetoward the cam 65 b a suitable spring, such as shown .i in Fig. 3 at 0.

It will be seen that with the table and pattern roll thus positivelydriven', a suitable pigment pattern is placed on both the transfersurfaces 20 and 21 at each com lete rotation of the table, andfurthermore, oth transfer segments are presented in their workingposition, at the front of the machine, on each rotation of the table.

The character of work shown in the machine is illustrated in detail onlyby way of example, and comprises a complete rectangular frame havingparallel sides A and A and relatively shorter sides B4 and B'. The

interior surfaces to be decorated, as with the grain pattern of thepattern roll, are all indicated at s and are beveled in downwardly diver'ng arrangement as shown, see Fig. 3. The inclination of the surfaces .9ma be varied as well as the general shape o the surfaces; for example,these may be concave or convex in different frames. The frame referredto above, is for automobile Windows and there are anchor prongs or lugsat the corners, indicated conventionally at At the front of the machine(at t e right in Figs. 1, 2 and 3 there is a work carrier comprising abar 2 pivotally supported, as on a suitable pin 73, carried by a bracketmember 75 ad]ustably secured to the front face of a main bracket 74. Thelatter is attached to the front face o f the member 4. The bracket 74,at the end opposite the pivot pin, carries another *bracket member, 76,which has its 'i1 er surface 76 isee Fig. 7) arranged to sli a 1y carrythe en 72 opposite the pivot.

To directly support and ide the work adjacent the segments 20 an 21, thebar 72 carries any suitable number of work uiding rollers 77. These maybe substantial y alike, and a detail of one is illustrated in Fig. 7. Asshown, the rollers have an under-cut effect at78 to clear the prongs pon the frames.

of the bar The manner in which the rollers support the work and resentthe successive inner surfaces .s to tlie transfer material, is wellillustrated in Fig. 3. The position of the rollers is inclined inconformity to the inclination of the inside surfaces s and thesesurfaces are presented substantially ilatwise to the transer material.

For controlling the printing pressure contact and for adjustment in casethe sides of the frames vary in thickness, the bar 72 is mounted formovement toward and away from the axis of the table. As shown in Fig. 1,there is an adjustment device, including a short toothed rack 8O insetinto the free end of the bai` 72 at the bottom thereof and meshing witha pinion 81 on a stub shaft 82, carried by the bracket member 76. Thepinion is arranged to be turned by means of a chain 83 which, as shown,is yieldingly anchored to a suitable arm 84 on the machine frame bymeans of a tension spring 85. The chain passes over a sprocket 86 on theouter end of the shaft 82, then downwardly to a suitable treadle 87 nearthe base of the machine. The

sp1-in 85 will normally pull the bar 72 outward y so as to relievepressure on the frame, whereby the operator may control the printingpre'ssure with his'foot onv the treadle, leaving his hands free tomanipulate the frame, as required. To place the Work, the operator restsone edge, for example, the longer edge A as in Fig. 8, against two ofthe rollers 77, those nearest the pivot pin, as shown in Fig. 2; seealso Fig. 8, as the segment 2() approaches the transferring position.Thereafter, by maintaining sufficient printing pressure, as by means ofthe treadle and associated mechanism, the segment will drive the framealong to the left (as the operator faces the machine) causing thetransfer material to contact with the entire inner surface s of the sideA, positioned between the rollers and the segment. The grainin operationperformed in this manner is stri ingly accurate, even at the corners,and the entire surface s is fully decorated in this operation withoutrequiring any touching up, assuming, of course, that the surface 20 isthe r uired length. Actually this surface is of slightly less lengththan the length of the surface to be grained for the reason that thetransfer material spreads slightly, due to the printing ressure, thuselongating the segment. During this operation, it is desirable to drivethe frame forwardly at the start by means other v than the transfermaterial. For thispurpose, any suitable adjustable abutment may beprovided in the foremost blocks 23; as illustrated, there are adjustablepins at 88 (screws for example) arranged to` contact with the surface .sof the frame member adjacent the oneabout to be rained. During thegraining operation, t 1e frame may be supported in the inclined positionshown, by any suitable arrangement, such as an overhead bar 90, havingits ends depending as at 91 and then extending inwardly as at 92 forattachment to the machine frame. The frames to be grained simply slidealong the bar 90 from one position to another, as will be obvious.

The succession of steps necessary, with the mechanism described, tograin a complete frame is illustrated in Figs. 8 to 11. It will be seenthat as the segment 20 moves from the position shown in Fig. 8 to theposition shown in Fig. 9, the inside surface of the frame element A iscompletely grained. The operator now lifts the frame and turns it ninetydegrees, presenting the frame element B to the segment 21, as shown inFig. 10.

Further, rotation of the table results in graining the surface s of theframe element B, this being shown as completed in Fig. 11. Next, theframe element A is rained as in the case of the element A, an finally,the

' frame element B.

Thevarious scraping arrangements for the transfer material arepreferably arranged as follows. After the segments 20 and 21 pass thegraining position, at the front ofthe machine, they are rotated past andin contact with a fixed scraper blade 100 on a suitable bracketarrangement 101 (see particularly Figs. 4 and 5), which scraper 100 maybe carried in fixed position cn a suitable upright bar or pin 102 on thebracket. This cleans the graining surfaces 20 'and 21.

The scraper itself, after each segment has passed may also be cleaned asby an oscillatlng cleaner arm 103 having a blade 104 adapted to wipeacross the front face of the blade-100. Any suitable arrangement forVoperating the cleaner arm may be used; for example, we have providedcams 105 on the bottom of the table 1 designed to push outwardly on asliding rack 106, which through a spur idler 107, drives a gear segment108, the latter carrying the cleaner arm. Preferably the action is toclean the blade 100 on the up-stroke of the arm 103 after the patterntransfer segment has passed the blade 100 and been cleaned thereby. Therack may be returned after operation by the cam 105 in any suitablemanner as by any suitable return spring, not shown. There is, of course,one cam 105 provided for each segment in order that the cleaning actionof the blade 104 will occur after each scrapingl action of the fixedblade 100. By the a ove arrangement each of the se ents 20 and 21 aftereach graining operation thereof have their graining sur-faces 20 and 21effectively scraped to clean off the excess pigment, before the segmentsagain encounter the pattern roll.

It has been found that in the operation of this machine, the front oradvancing edges of the segments accumulate a quantity of pigment asthese edges come into contact with It is obvious that this accumulationwould normally be spread onto the frame being grained. For example, inthe operation illustrated in Fig. 8, such as accumulation of pigment onthe surface 20 of the segment 20 would cause a smear of paint on theframe side B. To prevent this, we have provided swinging Scrapers forthe front edge of the segments, as illustrated in Figs. 1, 2 and 6.

Referring particularly to Fig. 2, there are scraper arms 110, one foreach segment 20 and 21, carrying respective scraper blades 111. The armsare pivotally supported on inclined pivot axes, substantially inaccordance with the inclination of the surfaces 20 and 21 of thetransfer segments. Suitable brackets for carrying these arms maycomprise upright members 112 adjacent openings 113 in the table. Themembers 112 have pins 114 supporting the arms 110, and gear segments 115rigid therewith, the latter being 1n mesh with gears or segments 116also carried on the bracket members 112. Suitably attached to the gears116 are depending pins 117 and these are moved to and fro by oppositelyacting face cams 118 and 119 on the table. For example, the cam 118operates on the bar 117 when the arm 110 for the segment 21 is in theposition shown in Fig. 2, to throw the bar to the left, as shown in Fig.6, thus rotating the arm 110 in a counterclockwise direction, from thedotted line position to the full line position. This, by the upwardmovement past the surface 21, effectively cleans the surface. Thescraper 111 is, in this last mentioned operation, carried into contactwith a revolving wiper head 120 mounted on a.y suitable shaft 121carried in a bracket 122 on the table. The scraper head is revolvedperiodically by a successive arrangement of pins 125 (one only beingshown) located on the top plate 6 to move the wiper arms 126 past thescraper blade 111 to y effectively clean the same. Suitable receptacledevices (not shown) may be provided in association with the scraperheads 120 to receive the pigment material cleaned off the scraperelements 111 by the wipers 126. After the scraper mechanism justdescribed, for the segment 21, has been carried around to a point nearthe scraper 100, the cam 119 on the top plate may then, through theagency of the pin 117, return the scraper blade 111 for provision ofmeans to scrape ofi' any pigment i material which may lie on thelowermcst surfaces of the scrapers 111 as the latter lie outa wardlyfrom the table, and may comprise a suitable brush arrangement,illustrated in Fig. 2 at 127, thus effecting a com lete cleaning of theblade 111, which, as has een previously described, has been cleaned onits opposite surface by the scraper arms 126.

In Fig. 12 is illustrated diagrammatically a modified arrangement ofmechanism or apparatus for carrying out the method above described. Thisdiffers from the previously described arrangement primarily in that theframes are not supported for rectilinearmovement while being grained.Instead there is rovided an arm'150 pivoted as at 151 about, or example,the axis of the table 1 and carrying a single pressure roller 152. Withsuch an arrangement, the table may be continuously or intermittentlydriven, that is to say, the table may be stopped during the actualgraining operation if desired. To grain a frame such as indicated at X,in bro-ken lines, the frame is placed between the pressure roller andthe segment 20 and the arm moved automatically or by the operator,manually, in a counter-clockwise direction, as shown, carrying it to theposition shown in broken lines. In doing so, one complete side of theframe is grained on its inside surface, and this operation is completedwhen the arm and frame assume the broken line positions. The frame isnow lifted and turned at right angles so as to present one of theshorter sides of the frame to the oncoming segment 21, as before. If themachine is intermittently driven, it is preferable to locate the pigmentapplying devices, that is to say, the pattern roll and its associatedmechanism, in such manner that the roll will be out of contact with bothsegments when the piece of work is in contact with either.

In Fig. 13 is illustrated still another arran'gement, particularly onein which the transfer segments are not fixed with relation7 to the tableas in the previously described arran ements. In this modification, thetable, mdicated at 155, is in the nature of two oppositely extendingarms, one of which carries a segment 156 for graining or decorating thelonger side of a frame and the other, 157, being or graining the shorterside of the same frame. In such an arrangement, the pattern applyingelements, for example a roll 158, plgment pump or like device 159, and ascraper 160, may be carried in fixed position, on, for example, anoverhead frame work 170, or in any other suitable manner, and ansuitable arrangement may be used to intermlttently turn the table. Anyconvenient scraper arrangement for the transfer segments 156 and 157 maybe used. Preferably there is a substantially fixed scraper 166 locatedin the general vicinity of the pigment applying mechanism and arrangedto scrape the pattern transferring surfaces of the segments 156 and 157just before the surface ortions encounter the pattern roll 158. buchscraper 166 may be supported in any convenient manner by the frame workof al machine, for example, the frame member 170.

The work, in case this has beveled inside surfaces, maybe supported ininclined position, as previously described, on a suitable guide bar 163.A series of pressure rollers are indicated at 164 for carrying theframes into contact with the segments. These may be adjustably andmovably supported in any suitable manner. One advantage of anarrangement such as shown in Fig. 13, is that it enables the decorationof frames and the like on the inside surfaces, where these includearched effects on comparatively shortradii, such, for example, asindicated at Y in Fig. 14. In the case of a curved frame member or aframe -member having both curved and straight portions, only onepressure roll 164 would have to be used during the decorating operationon such frame member. In such case, the remaining pressure rollers couldbe moved out of the way, permitting the frame to swing as required, forexample as suggested in Fig. 12.

It will be understood that with the arrangement shown in Fig. 13, itwill be practically necessary to drive the segments 156 and 157 in suchmanner that they will be properly inked by the pattern roll with thedesired pattern and in such manner that the advancingl edge of eachsegment will be properly located with respect to the pressure rollers164, at work starting position, for example, as illustrated in Fig. 13.No driving arrangement is illustrated, but any suitable gearingmechanism may be used. For example, one or more suitably driven gearwheels, may pick up and turn both segments 156 and 157, as' required tocarry out the necessary movelments thereof, with the arm member 155temporarily held in the position shown, as well as in the reversedposition (156 in position to contact with the pattern roll).
